To all whom it may concern:

VBe it l'nownthat I, CHARLES B. TAN MAKER, a citizen ofthe United States, ing` at indianapolis, in the county er and State of Indiana, have invented and usefull Drum, of which the olioivin 'a speoication.

In the manufacture of druns hereto-fore .it has heen a common practice to adjust the,

flesh' hoop longitudinally of the shell hy means of hooked clamping rods act-ing upon two hoops havinor thesanie thickness, and diameter as-the esh hoops and, owing; to the fact thatthese hoops become distorted either permanently or temporarily hy nnskilled manipulation ofthe Clamping rods,

the iiesh hoops are many times twisted upon the shell 1n such manner as: to' deaden the sound of the druni and to deaden the reaetion of the heads upon the sticks and snares.

fille-.object` of my present .invention is,v therefore, to 'produce a drum `cgonstruetion inwhioh these difficulties shall he obif'iated, thereby producinga drum having a much vmore hrilliantl tone than has heretofore.

instead of the-ordinary hoops, hoiveY Jr, l provide a hoop 14 L-shaped in cross mtion so that there ,is formed an annular r pocket l5 in which the iesh hoop lf3 is freely seated. Each hoop Mis provided with ra.- dially extending ears 16 provided. with a perforation 17 parallel to the axis le hoop. Each perforationv 17 at its outer en lby .a combined --tuhular ses* is 'provided with hemispherieal seat 18.' The two hoops drawn toward each other clamping rodeomprising a i upd a eoper u .ernally threaded at 22 tn 'eased portion 7 of rod 2l.
